FORGE.

Specification of Letters Patent.

Patented Get. 19, 1909.

Application led February 6, 1909. Serial No. 476,453.

To all whom it may concern.'

Be it known that l', JOHN PHILIPSKI, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented a new and useful Improvement in Forges, of which the followingis a specification.

This invention relates to a forge furnace, and the object of theinvention is to eliminate the smoke nuisance now present with furnacesof this kind, thereby preventing the same from filling the shop in whichthe forge is located.

The invention consists of the novel features of construction hereinafterdescribed, pointed out in the claims and shown in the accompanyingdrawings, in which:

Figure 1 is a front elevation of a furnace with my invention appliedthereto. Fig. 2 is a plan view, the smoke pipe being shown in section:Fig. 8 is a side elevation: F ig. 4 is a central vertical sectionthrough the blower. Fig. 5 is a detailed sectional view of certaincommunicating pipes and a swinging valve.

In these drawings, l represents a furnace provided with sliding doors 2and a depending extension 3 closed at the bottom by a door 4 to preventashes from dropping from the furnace. The blower consists of a fancasing 5 divided by a partition 6 in two separate non-communicatingcompartments in which are arranged fans 7. These fans are mounted upon ashaft 8 which shaft is driven in any suitable manner. Leading from oneof these compartments, which compartment has suitable side openings foradmittance of air is an air pipe 9 which discharges into the furnacethrough the extension 3.

Leading from the upper top portion of the furnace is a pipe 10 whichdischarges smoke from the combustion chamber of the furnace in the othercompartment of the blower, and from this last mentioned compartment apipe 11 leads to a smoke stack 14, the said pipe being parallel througha portion of its length with the pipe 9. The pipes 9 and 11 are adaptedto communicate with each other through the suitable opening, suchcommunication being controlled by a swinging valve 12 operated by avalve rod 13. The valve 12 is so hinged that when opened to givecommunication between pipes 9 and 11 it will rest diagonally across pipe9 and will cut off communication between the air side of the blower fromwhich the pipe 9 leads and the furnace. It will be noted therefore thatwhen valve 12 is open the blower will supply air to the pipe 11 thusincreasing the draft of smoke through the pipe l() and the smoke side ofthe blower, the smoke passing from the blower to the stack through pipe11. By thus creating a strong draft from the upper part of the furnacethe same will be kept clear of smoke, thus preventing its escaping fromthe furnace into the shop, when the doors are open. The advantages ofthis construction will be obvious to those using forges of this kind.

What l claim is 1. The combination with a furnace and a smoke stack of adouble blower, an air pipe leading from the blower to the furnace, apipe leading from the upper portion of the furnace to the blower, a pipeleading from the blower to the smoke stack, and a swinging valve adaptedto cut off communication through the air pipe between the furnace andblower and place said air pipe into communication with the pipe leadingto the smoke stack.

. 2.- The combination with a forge furnace and a smoke stack, of adouble blower di vided into separate compartments, an airv pipe leadingfrom one compartment to the lower portion of the furnace, a pipe leadingfrom the other compartment to the smoke stack, said pipes having valvecontrolled communication with each other, and a pipe leading from thetop of the furnace to the last mentioned compartment.

3. The combination with a furnace and a smoke stack, of a blower dividedinto noncommunicating compartments, means for conveying smoke from thefurnace to one of said compartments, a pipe leading from saidcompartment to the smoke stack, an air pipe leading from the othercompartment and communicating with the second mentioned pipe, and aswinging valve controlling such communication.
